采用原子层沉积(ALD)法在400℃的可伸缩床反应器中制备了高度分散的Fe纳米粒子。在CO氧化反应中，Fe/SiO_2催化剂上的Fe_2O_3起着至关重要的作用。在超过300h的CO氧化反应的长期稳定性试验中，在550℃时，Fe/SiO_2几乎没有活性下降。
Highly dispersed Fe nanoparticles (NPs) were deposited on SiO2NPs by atomic layer deposition (ALD) in a scalable fluidized bed reactor at 400 ºC. In CO oxidation reactions, over the Fe/SiO2catalyst, Fe2O3played a vital role. In a long-term stability test of more than 300 h of CO oxidation reaction, there was almost no activity decrease of Fe/SiO2at 550 ºC.Graphic Abstract
